As last year, Booking.com is hosting the event and as last year, canal boats will bring attendees from the conference venue to Booking.com headquarters.

This event involves some planning: Percona needs to arrange for canal boats and Booking.com needs to order food and drinks and plan for catering staff. In both cases, too much or not enough is bad for obvious reasons, and this is why we ask you to register.

The normal sales end soon. After that, commitments need to be made and we will have less flexibility for accommodating more people.

I agree on the suggestions for relay-log-info-repository and relay-log-recovery: they are needed for crash safe replication, and having crash safe replication enabled by default is a good thing. I have doubts about master-info-repository: I do not see what benefits are introduced by this change. I have much bigger doubts about sync-master-info and sync-relay-log: those changes bring an illusion of safety, which is bad. Let's dive in more details about those parameters.
